Lux describes the perceived illumination of a known space.
Lumen measures how much visible light is produced by an object.
To use Lux To Lumens Calculator, follow the following steps-
- Enter illuminance in lux.
- Enter unit of area as either ft2 or m2.
- Enter radius of the spherical light source, or you may enter directly the surface area.
- Click on Calculate button, and you will get the result in lumens.
Lux To Lumens Conversion Formula
Following formula converts lux into lumens.
ΦV(lm) = 0.09290304 × Ev(lx) × A(ft2)
ΦV(lm)= Luminous flux in lumens.
Ev(lx) =Illuminance in lux.
A(ft2)= Spherical surface area.
0.09290304 is a constant value.
